apnea and Brain Ischemia

apnea has been researched along with Brain Ischemia in 13 studies

Apnea: A transient absence of spontaneous respiration.

Brain Ischemia: Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.

"Apnea is a known response of concussive head injury."7.70The early critical phase of severe head injury: importance of apnea and dysfunctional respiration. ( Anderson, RE; Atkinson, JL; Murray, MJ, 1998)
"Under cerebral ischemia or aortic stenosis, changes in plasma and adrenal corticosterone (CS) levels before and after cardiac arrest-preceding type (CPT) and apnea-preceding type (APT) sudden death were examined to determine the response of the hypophyseal adrenocortical system in Wistar rats."7.67[Experimental studies on stress hormones at the time of sudden death (II)--Differences in adrenocortical hormone levels of cardiac arrest-preceding type and apnea preceding type sudden death under cerebral ischemia or aortic stenosis]. ( Douge, K; Ming-Chang, T; Tsunoda, K; Watanabe, T, 1989)
"To evaluate the current standards for apnea testing in the evaluation of brain death in children."4.80Increased apnea threshold in a pediatric patient with suspected brain death. ( Pollack, MM; Vardis, R, 1998)
" The following proposals are advanced: 1) the lack of any set of clinically detectable brain functions does not provide a safe diagnosis of brain or brain stem death; 2) apnea testing may induce irreversible brain damage and should be abandoned; 3) moderate hypothermia, antipyresis, prevention of arterial hypotension, and occasionally intra-arterial thrombolysis may contribute to good recovery of a possibly large subset of cases of brain injury currently regarded as irreversible; 4) confirmatory tests for brain death should not replace or delay the administration of potentially effective therapeutic measures; 5) in order to validate confirmatory tests, further research is needed to relate their results to specific levels of blood supply to the brain."4.80Implications of ischemic penumbra for the diagnosis of brain death. ( Coimbra, CG, 1999)
"Apnea is a known response of concussive head injury."3.70The early critical phase of severe head injury: importance of apnea and dysfunctional respiration. ( Anderson, RE; Atkinson, JL; Murray, MJ, 1998)
" Reactive hyperemia, apnea, and vasodilatation appeared to be changed in ischemic and normal brain."3.68Early detection of regional cerebral ischemia using high-speed MRI. ( de Crespigny, AJ; Kozniewska, E; Kucharczyk, J; Moseley, ME; Roberts, TP, 1993)
"Circulation time (CT) is markedly prolonged when arterial pressure is extremely elevated by global brain ischemia which elicits also bradycardia, decrease in cardiac output and apnea in anesthetized rabbits."3.68[Prolongation of circulation time during brain ischemia-induced hypertension in the rabbit]. ( Kanno, T; Shimizu, T, 1992)
"Under cerebral ischemia or aortic stenosis, changes in plasma and adrenal corticosterone (CS) levels before and after cardiac arrest-preceding type (CPT) and apnea-preceding type (APT) sudden death were examined to determine the response of the hypophyseal adrenocortical system in Wistar rats."3.67[Experimental studies on stress hormones at the time of sudden death (II)--Differences in adrenocortical hormone levels of cardiac arrest-preceding type and apnea preceding type sudden death under cerebral ischemia or aortic stenosis]. ( Douge, K; Ming-Chang, T; Tsunoda, K; Watanabe, T, 1989)
" Further reduction of BBF (avg of 42% of control) first produced intense tachypnea and then (30--40% of control) caused apnea that was reversible."3.66Effects of graded reduction of brain blood flow on ventilation in unanesthetized goats. ( Chapman, RW; Edelman, NH; Santiago, TV, 1979)
"The dog was presented with seizures and neurological deficits consistent with a left brainstem and multifocal/diffuse forebrain lesion after an asymptomatic interval of 72 hours following the ischaemic event."1.35Sequential magnetic resonance imaging changes after suspected global brain ischaemia in a dog.
